Keep in mind that while Wegman's is huge... there are ALOT of people in it and it feels like it's much smaller.
Agree about the upscale stuff, but after a few years, much of it disappeared leaving only the items they sold a lot of. They've also replaced a lot of the national brands with their own brand, leaving ordinary groceries limited to only a few brands.
I would say 1/3 of the store is dedicated to prepared food and take out.
As for coffee... would you like some of the ground or beans version? I'm not 100% certain they sell it, but will gladly check for you. I never buy their sandwiches - there's an Italian deli across the street that I think is far superior
